Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
nullRefer to Fig. 1～2，In the utility model embodiment，A kind of magnetic braking apparatus of threephase asynchronous，Including rotary shaft 2、Prop up support plate 4、Permanent magnet 5、Secured core 8、Brake disc 11 and protective cover 13，Described rotary shaft 2 is arranged in protective cover 13，Rotary shaft 2 and protective cover 13 junction are arranged with bearing 3，Support plate 4 and a location dish 12 are installed in protective cover 13，Prop up support plate 4 and location dish 12 is arranged on the two ends of protective cover 13 and is fixed on bearing 3，Prop up and connected by the many axis of guides 9 between support plate 4 and location dish 12，Slide to be provided with on the axis of guide 9 and press plate 1，Press plate 1 center and be provided with the through hole passed for rotary shaft 2，Press plate 1, with support plate 4 contact surface, multiple secured core 8 is installed，Solenoid 7 it is provided with in secured core 8，Secured core 8 is by coming excitatory to solenoid 7 energising，Secured core 8 lateral surface connects permanent magnet 5 by spring 6，Permanent magnet 5 is embedded in a support plate 4，It is identical that permanent magnet 5 is oppositely arranged face magnetic with secured core 8，So that repelling with permanent magnet 5 after secured core 8 is excitatory，Slide away from a support plate 4 so that pressing plate 1 along the axis of guide 9，Press plate 1 opposite side and be fixed with external friction steel disc 15，Press and between plate 1 and location dish 12, be provided with brake disc 11，Brake disc 11 is fixed with interior friction steel disc 10 near the side of external friction steel disc 15 by fixing bolt 14，Brake disc 11 and interior friction steel disc 10 are fixed in rotary shaft 2.
During use, rotary shaft 2 rotates so that hard-wired brake disc 11 and interior friction steel disc 10 common rotation on it, when needs are to rotary shaft 2 braking regulation, solenoid 7 energising makes secured core 8 excitatory, owing to excitatory rear secured core 8 is identical with permanent magnet 5 magnetic being oppositely arranged, produce relative thrust, slide away from a support plate 4 so that pressing plate 1 along the axis of guide 9, the gap pressed between the interior friction steel disc 10 in the external friction steel disc 15 of plate 1 opposite side and brake disc 11 is gradually reduced, until external friction steel disc 15 compresses interior friction steel disc 10, thus reach the purpose of braking.
Operation principle of the present utility model is: the magnetic braking apparatus of described a kind of threephase asynchronous, simple in construction, easy for installation, it is easy to manipulation, makes secured core 8 excitatory, so that external friction steel disc 15 compresses interior friction steel disc 10 by solenoid 7 energising, realize the braking to brake disc 11, fast response time, the stable height of braking, good braking effect.
